What complication may arise from improper insulin administration?

Hypoglycemia is a significant and potentially dangerous complication that can arise from improper insulin administration. When insulin is administered incorrectly—whether through an inappropriate dose, timing, or technique—it can lead to a drop in blood glucose levels. Insulin lowers blood sugar by facilitating its uptake into cells for energy. If too much insulin is given or if it is given without sufficient carbohydrate intake, the body may not have enough glucose to meet its energy needs. This can cause symptoms such as shakiness, sweating, confusion, irritability, and in severe cases, loss of consciousness or seizures.

While over-sensitivity to insulin can occur in some individuals, it is not a common complication associated with improper administration. Increased energy levels and weight gain are not directly linked to improper insulin use; in fact, the opposite is often true, as insufficient insulin can lead to fatigue and weight loss due to the body not effectively utilizing glucose.
